A friend posted a touching message in Facebook, to a dearly departed friend called KD. That led me to post the following on my wall.

In my school days in Chennai, KD was used as description of criminals. Does anyone know how that came about?

I got two responses which satisfied me.

Nandu Pillai KD = Known Dacoit .

Arvind Rajgopaul short form of ‘known delinquent’.

Then my friend Rajesh suddenly popped up with this message in the same thread.

Rajesh Mehta vanakam sir how are you

Vanakkam is Tamil for Salutations.

Was he implying that I am a KD?

To prevent any misunderstandings, I posted this as a reply to him.

Rajesh Mehta I was never a KD. Vanakkam any way.
